STANCHIONQ SPECIFICATION forming part of Letters Patent No. 772,520, dated October 18, I904.

Application filed March 30, 1904;. Serial No. 200,831. (No model.) i

To all whom it may concern:

Be it known that I, EDWARD J. KIRK, a citizen of the United States, and a resident of Camden, in the county of Camden and State of New Jersey, have invented a certain new and useful Improvement in Stanchions, of which the following is a specification.

The object of the present invention is to produce. a simple, durable, and efficient cattlestanchion which may be easily manufactured and which'may be automatically released.

- A further object is to provide a stanchion of the character referred to which shall be so constructed as that a series thereof may be connected to operate simultaneously and reliably.

anism for such stanchions, which may not be operated by the horns of the cattle.

Incarrying out'the invention the stanchion is preferablyformed of angle-iron and supported above and below either by chains or swivels or such other mechanism as may be desired. One side of each stanchion is movable relativelyto the other, the upper end thereof carrying a latch coacting with a tongue formedon the other member of the'stanchion, and such latch is connectedby means of a chain or other suitable device with a rod or wire, the operation whereof trips the latch and permits the movable side of the stanchion to be opened.

v The invention is illustrated in the accompanying drawings, in which-.

Figure 1 is an elevation illustrating two of a series of stanchions employing my invention. Fig. 2 is an enlarged detail view illustrating the major part of one of the stanchions and its supporting device; and Fig. 3 is a crosssection on the line 3 3, Fig. 2, but showing the latch in operative position.

Referring to the drawings, in which similar letters denote corresponding parts, it will be noted that a frame of ordinary construction is employed, this being here shown as comprising upper and lower horizontal bars A B and uprights a a a, connecting the same. The

stanchion 0, made preferably of angle-iron or of other iron having an outwardly-extending web, such as the web 0, is formed in two parts d cl", pivoted together at their lower ends at ri and such pivot is in the present instance utilized for the connection of the lower end of passing through a cone-shaped opening 6Z6 in.

said frame-bar A in order topermit freedom v of movement of the stanchion. A further object is to provide latch mech- The outwardly-extending web of the free end of the member (Z of the stanchion is cut away, as clearly shown in Figs. 1 and 2, such end being provided with the tongue 0, with which coacts the latch E.

' The laterally-projecting portion (Z ofthe angle-iron forming the member CZ of .the stanchion is preferably recessed at (Z and the extremity of the movable member (Z of the stanchion flattened out, as clearly shown in Fig. 2, to form a bearing for said latch The latch E is here shown in the form of a bell-crank lever pivoted at 0 upon the fiat-- tened .upper extremity of the movable -member d of the stanchion. Its free end 0 is provided with a recess adapted to coact with Theupper end of the apshown as comprising a bar secured at the upper end of the movable member (Z' of the stanchion and extending substantially at right angles thereto. This bar and the flexible connection betweenthe latch'E and the operating-rodF are so arranged as that when the stanchion is closed said chain will be protected against accidental operation by the horns of the animal confined by the stanchion, as indicated in Fig. 1.

As will easily be seen, the stanchion may readily be closed and locked in such closed position by means of the latch mechanism above described. To open the same or any number of such stanchions which may be employed, it is only necessary to move the operating-rod F to the right. This movement of the rod through the connecting-chains 0 trips each latch E, freeing the same from engagement with the tongue 6 and moving the member (Z of the stanchion or permitting the same to move sufiiciently far to the right to open the stanchion to the position shown in Fig. 2.

Having now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

1. The combination with a suitable frame, of a stanchion movably supported therein, said stanchion comprising two members hinged together at their lower ends, the upper end of one of said members being provided with a tongue and the upper end of the other member being provided with a latch coacting therewith and an extension adjacent to said latch and coacting with said latch to prevent accidental displacement thereof, an actuating-rod, and a connection between the same and said latch, substantially as set forth.

2. The combination with a frame, of astanchion movably supported therein, said stanchion being formed of angle-iron and comprising two members hinged together attheir lower ends, the web of such angle-iron adjacent to the upper end of one of said members being cut away and such end provided with a tongue, and the upper end of the other of said members being flattened out and provided with a latch coacting with said tongue, an extension on said last-named member adjacent to said latch and coacting therewith to prevent accidental displacement thereof, and

means for operating said latch, substantially as set forth.

3. The combination with aframe, of a stanchion movably supported therein, said stanchion being formed of angle-iron and comprising two members hinged together at their lower ends, the web of such angle-iron adjacent to the upper end of one of said members being cut away and such end provided with a tongue, the upper end of the other of said members being flattened out and provided with a latch coacting with said tongue, an extension adjacent to said latch and coacting therewith to prevent accidental displacement thereof, a movable operating-rod, and a connection between the same and said latch, substantially as set forth.

4. The combination with a frame. of a stanchion movably supported therein and comprising two members hinged together at their lower ends, a latch for connecting said members near their upper ends, a rod, a connection between the same and said latch, and a guard for said connection, substantially as set forth.

5. The combination with a frame, of a stanchion movably supported therein, said stanchion being formed of angle-iron and comprising two members hinged together at their lower ends, the web adjacent to the upper end of one of said members being cut away and such member provided with a tongue, the 11p per end of the other member being flattened out and provided with a latch, an operatingrod, a flexible connection between the same and said latch, and a guard for said connection, the same being secured to the upperfiattened end of that member of the stanchion carrying the latch, substantially as set forth. This specification signed and witnessed this 26th day of March, 1904.
